The MyPaint brushlib is now maintained in a separate git repository. Its new home is also on Gitorious, at https://gitorious.org/mypaint/libmypaint/, so it hasn’t moved far! We’ve done this because there are more projects using this code, or wanting to use it, than just MyPaint. The MyPaint project now includes brushlib as a git submodule.

The practical upshot of this for users is that you may see some unexpected errors if you’ve been tracking MyPaint development through git for a long time. If you’ve just updated your clone using “git pull”, and your build is failing due to a missing file:

After fetching the missing dependencies, the build procedure should work as it did before.

If you switch between branches a lot, you may find yourself having to do this quite a lot: not every branch of MyPaint out there know about the submodule yet. Sorry about that; please excuse the dust.

The basics of this are recapped in the updated README file, and more information on working with git and submodules is available online or in print in the Pro Git book, chapter 6.6 Git Tools – Submodules.
